Development of Stearic Acid Coated Fly Ash Reinforced ...

2016-9-9 · Stearic acid was used as a coupling agent between recycled polypropylene and fly ash particles. The concentration of the coupling agent was varied from 1 wt% to 5 wt% with respect to the fly ash weight. The glass transition shifted to a higher temperature in all the treated composites, the highest being in RFASA1 at + 6.3oC from that of -1.6oC in RFASA0. This reflects restricted chain mobility in the treated composites due to enhanced interfacial interaction. The thermal stability also increased with maximum delay in the onset of degradation in RFASA1 at 269o C due to better interfacial bonding between the filler and matrix. The coupling agent also increased the activation energy of the composites. Thus, a renewable, low cost chemical like stearic acid can be used as an effective coupling
